CAN-CAPPING MACHINE.

SPECIFICATION forming part of Letters Patent N o. 448,04*?,dated March 10, 1891.

Application filed November 13 1890. Serial No. 371,284. (No model.)

To all zuwn it Hefty concern:

Be it known that I, MATHrAs JENSEN, of Astoria,in the county of Clatsop and State of Oregon, have invented a new and Improved Can-Capping Machine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved can capping machine which is simple and durable in construction 1o and specially designed for automatically applying the caps on a certain class of 'canbodies, such as made of uniform diameter and without exterior projecting seams.

Theinvention consists ot' Va conveyer mounted to swing vertically and longitudinally a'nd adapted to carry the can-body forward to a stationary bed-mold, and a clamping-mold actuated from the said arm and adapted to clamp the can-body on the said stationary zo bed-mold while the caps are forced onto its.

ends.

The invention also consists of certain parts and details and combinations of the'same, as will be hereinafter fully described, and then 2 5 pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding` parts in all the figures.

Figure l is a side elevation of the improvement. Fig. 2 is a sectional side elevation of the same on the line ac of Fig. 3. Fig. 3 is a plan View of the improvement. Fig. 4 is a plan view of the conveyer and the mechanism for operating the same. Fig. 5 is a transverse section of the improvement on the line y y of Fig. 3. Fig. 6 is a sectional side elevation of the improvement in different position from the one shown in Fig. 2, and Fig. 7

4o is a perspective view of one of the retainingblocks for the caps.

The improved can capping machine is mounted on a suitably constructed main frame A, in which is journaled in suitable 4 5 bearings the transversely extending main driving-shaft B, connected in the usual manner wit-h suitable machinery for imparting a rotary motion to the said shaft in the direction of the arrow a. On the main driving- 5o shaft B is secured a gear-wheel B in mesh at opposite sides with the two gear-wheels B2 andBS, secured on the shafts O and C', re-

spectively, also mounted to turn in suitable bearings in the main frame A and extending parallel with' the main drivingshaft B.

At or near the middle of the shafts O and O are formed the crank-arms O2 and O3, respectively, pivotally connected with the ends of conveyer D, which receives a swinging motion by the said crank-arms when the main driving-shaft B is rotated and the shafts O and C are set in motion thereby. The conveyer D is provided on its top with two recesses D and D2, of which the recess D' is adapted to carry a can-body from a resting-place E onto the bedmolds E, between which the said conveyer D swings, and which are secured on longitudinally-extendng plates F, supported on posts F', secured to the top of the main frame A.

The resting-places E of the can-bodies are formed on the lower ends of upwardly-inclined bars E2, secured to the inside face of the plates F, and on the upper end of which are placed the can-bodies to roll down to the resting-place E. On the opposite side of the fixed bed-molds E are arranged the downwardly-inclined bars E3, on which the canbody is placed by the conveyer D after the caps are put on, the capped cans then rolling off of the machine. Each of the fixed bedmolds E is semicircular on top and onto it is adapted to pass a clamping-mold G, fitted to slide vertically in suitable bearings F2, formed on the plates F. In the lower edge of the clamping-mold G is arranged a semicircular opening corresponding to the semicircular opening or recess in the top of the bed-mold E, so that when the clamping-mold is in the lowermost position a full circular opening is formed by the same and the bedmold. This circular opening is somewhat less in diameter than the inside diameter of the caps to be put on the ends of the can-bodies.

The two clamping-molds G are connected with each other by a pivot-pin G passing through a lever H, extending rearwardly and pivotally connected by a pivot-pin H with the upper end of a link H2, pivoted at H3, between the insides of the plates F. The free or forward end of the lever H carries a pivotpin H4, on the ends of which are pivot-ed the down wardl y-extend i un' rods I, secured at their lower ends in pivots l', mounted to turn near one of the ends of the conveyer D. When the main shaft B is' rotated and the conveyer D swung, as previously described, the pivots I' and the rods I impart a swinging motion to the lever I-l, so thatJ the clamping-molds G are moved vertically up and down in their bearings F2, for the purpose hereinafter more to fully described.

In order to bring the clamping-molds G into the proper position relative to the bed-molds E, the rods I are threaded at their lower ends and nuts I2 and I3 screw at these lower ends z5 on opposite sides of the pivots I', so that by adjusting the nuts the position of the lever H can be regulated to bring the clamping-molds G into the properposition. On each ot' the bed-molds E extends outwardly a cylinder J zo somewhat larger in diameter than the circular opening formed by the bed-mold and the clamping-mold previously described. Each cylinder J is secured or formed 011 the respective plate F, and is provided in its side 2 5 with a slot J through which the cap for the can-body can pass into the cylinder J.

Each slot J "registers with a chute K, inclined upwardly and secured to the outside of the respective plate F. The chute K is of 3o suoli a width as to support the can-caps one behind the other and is inclined in such a degree that the caps successively roll into the cylinder J. The outer end of each cylinder J is somewhat reduced in diameter, and is reduced and contains a plunger or piston L,

connected at its outer end with a lever N, fulcru med on a suitable bracket projecting from the respective plate F. Each lever N is provided with a forked end, of which the prong 4o N' passes into a slot L', formed in the respective plunger L. This prong 011 the swinging of the lever serves to move the plunger L outward in the cylinder J. In the other prong N2 screws a set-screw N3, adapted to abut against the outer end of the plunger L, so as to move the latter inward, when the lever N receives a swinging motion. On the free end of eachv lever N is held a friction-roller O, engaging a cam-groove in a cam P, secured to 5o the shaft C, previously mentioned. Vhen the latter is rotated on revolving the main shaft B, as is previously described, the cams P irnpart a swinging motionsiin ultaneously to the levers N, so that the plungers L, connected 5 5 with the said levers, are moved simultaneously inward or outward inthe cylinders J to force the caps onto the ends of the canbody, then clamped on the stationary bedmolds E. When the plungers L are in their 6o outermost position, the slots J in the the cylinders are open, as is plainly illustrated in Fig. 5, to permit the lowermost cap in the respective chute K to pass into the respective cylinder.

An arm Q is provided for each chute K and arranged in line therewith and adapted to engage the front edge of the lowermost cap in the chute, so as to prevent it from passing into the slot J until the proper time arrives. Each arm Q is formed on a lever Q', pivoted at Q2 to the outside of the respective plate F, the free end of the said lever heilig engaged by the free end of an arm R, secured on a shaft R', extending transversely and mounted to turn in the two plates F. On the shaft R', between the plates F, is secured an arm R2, curved, as is plainly illustrated in Fig. 6, and adapted to rest ou top of the can-body lifted by the conveyer D from the resting-place E' onto the stationary bed-molds E. Thus when the upward swinging motion of the conveyer D takes place and a can-body is lifted from the resting-place E' upward, then the top of the can-body presses against the under side of the arm R2, so that the shaft R' is turned in its bearings, and the arms R act on the free ends of the levers Q', so that the latter swing upward, and their arms Q move out of the path of the respective lowermost cap held in the chutes K, so that this lowermost cap can pass through the slot J into the respective cylinder J. 'lhe arm R2 drops into the position shown in Fig. 2 as soon as the respective can-body has been placed in the bed-molds, so that the arms Q quickly move downward to engage the next-following caps in the chutes K to retain the said caps in place.

In order to retain the cap in place while moved by the respective plunger from the slot J to the end of the can-body, a loose block S is placed in the top of each cylinder J near its front end, the said block by its weight resting-on top of the cap, thus holding the same in place during the movement of the cap through the inner end of the cylinder J. rlhe blocks are prevented from passing` too far into the cylinders by transverse pins s, as shown in Fig. l. These pins scross the slots in which the blocks S work and rest when the blocks are in their lowest or innermost positions on top of the cylinders J. The operation is as follows:

The can-bodies are fed one after the other down the inclined bars E2, so that the lowermost body rests in the resting-places E. The chutes K are filled with caps, so that their openings extend inwardly, the lowermost caps being arrested by the arms Q. Now, when the main driving-shaft B is set in motion, a similar rotary motion is imparted to the shafts C and C', which by their crank-arms C2 and C3 impart a vertical and longitudinal movement to the conveyer D, which by its front recess D' engages the lowermost can-body in the resting-place E', lifts the same upward and then by its forward longitudinal movement places the can-body into the semicircular recesses of the bed-molds E. By this upward movement of the conveyer and its canbody two caps are released in the chutes K, the said caps passing through the slots J into the cylinders J. When the can-body is in position on thebed-molds E, the conveyer D in itsdownward movement deposits it there and imparts IOO IIC

a downward swinging motion to the lever H, so that the clamping-n1olds G are forced downward to firmly engage the top of the can-body near the ends. The ends of the can-body slightly project into the somewhat larger cylinder J. The out-er faces of the bed-molds E are chamfered out to permit the inner endsvof the cylinders J to extend under thelower halt of the ends of the can-body, so that said cylinders may guide the caps while entering onto the can-body. (See Fig. 5.) The molds G are also chamfered out like the bed-molds E, so that no parts thereof interfere with the caps while entering onto the can-body. The action of the cams P forces the levers N to swing,so that the latter moves the plungers L inward, thereby forcing the caps in the cylinders J, so that the caps enter onto the ends of the canbody j ust as the molds G are on theirlowermost position and firmly clamping the can-body onto the bed-lnold E. The conveyer D and the molds G are now again commencing to move upward, while the plungers L continue inward till t-he caps are properly forced onto the can-body, and as the conveyer D moves farther upward its recess D engages a new canbodyand carries it over the front walls of the bed-molds E, while the recess D2 engages the capped can and carries it over the rear walls of the bed-mold E, and on the downward movement of the conveyer D the new can-body is lowered into the bed-mold E, while the capped can is lowered onto the bars E3, down which it rolls off the machine.

In order to regulate the inward movement of the plunger L so as to bring the caps into proper position ou the ends of the can-bodies, the set-screws N3 are adjusted at the ends of the levers N, so as to accomplish the desired result. Aproper movement of the clamping'- molds G is had by adjusting the nuts I2 and I3 at the ends ot' the rods I previously mentioned.

I am aware that the mode of automatically rounding and holding the can-body by means of clamping-molds while the cap is guided in a cylinder and applied to the can-body by means of a reciprocating plunger, as above described, is the same in principle as shown in patent, No. 235,700, granted to George H. Pierce, December 21, 1880; but I deem that my invention as described above is an 'improved mode of applying that principle, and that it contains no inventions as claimed in other patents, except the device for each canbody to release its own cap, which is here substantially the same as in my patent, No. 376,804, dated January 24, 1888.

Having thus fully described my invent-ion,
